Well if you want cheap, I would suggest using Edelbrock stuff all the way around.

idk, you could get the cobra w/ any motor, just about. my friend has a nice 76 cobra w/ a 2.8 4 speed nice looking car, but a dog, espc. since he blew a hole in the side of the tranny...

Wow, thats great I forgot that you could order those cars with any engine. Most of them had the 302 from what Ive seen/experienced though.

ya sure. the engine in the car is definetly a 302. I am not sure what the transmission is though. my friends dad also said that this car is a problem car is this true? I would also like to know if its worth while to put a bigger engine into the car or just improve the current engine.

Well this was a problem car if it had the 2.8L engine like dodger65 stated. Yours has the 302, so it shouldnt give you much trouble. However this year of the 302 was an incredibly under powered one. I think it only had something like 160hp. It might have been closer to 200hp but I dont remember. Anyway, it wouldnt be to much trouble to put a bigger engine in there. Its got a big engine bay. But if you want to keep it original, then use the engine that its got in it, rebuild it, and do a few performance mods to it.

Ok well yank that old 302 out of there and sell it and then drop in a 351 Windsor or a 351 Cleaveland. The Cleaveland would be cheaper than the Windsor. Both those engines are a nice basis for a good speed project.

Ok, the Mustang II is actually a fairly solid car to build from. It's also old enough that you don't need to worry about emissions. The problem areas were emissions related, as well as some typical older car electrical issues, which can be cured by making sure all conections and grounds are good.

The 302 in that car, stock, would be a low compression engine making not much more than 100 hp. The heads are large chamber as well. It won't matter what you do with cams and intake/exhaust as the compression ratio and heads are your limiting factors.

Luckily you can find swap meet or used heads that will wake that car right up. I prefer the early 289 hi po heads with the small combustion chambers, and then port them for better flow. You can often find them for about $100 each. Much cheaper than later 5.0 heads. Then, have the block overbored .030. Any good machine shop should be able to accomplish this for fairly cheap. If you go to Summit or PAW, you can get a complete rebuild kit for that engine for cheap, with overbored, higher compression pistons. If you go with a 10:1, .030 over piston set, you can still run on pump gas easily. Match that up with a swap meet Edelbrock Torker 289 dual plane intake manifold (or equivalent) and a Holley 650 double pumper (or 700-750 cfm if you can find it, but don't get an Edelbrock/Carter.) An Edelbrock Performer RPM cam grind will take advantage of that compression ratio to give you a 6500-7000 rpm redline, while still being streetable.

You could probably build this engine for under $1500 if you shop carefully. And you'd be looking at about 300+ RWHP with some good equal length headers an 2 chamber flowmasters (cheap mufflers, but they'll work. Borlas are better, as are a couple others, but costs can sometimes be an issue.)

As for the transmission, if it's an automatic, it's most likely a C4. A B&M shift improver kit will tighten it right up, and give you hard launches, firm fast shifts, and extended transmission life. $50 or so, and easy to install.

After that, you're looking at traction and suspension.

He could do all this to that old 302, but then again wouldnt it just be easier to drop in a 351 Cleaveland?

He would already have better compression to start with, so he would have to deal with bumping it up. You can get these egines for fairly cheap used if you look around enough. Plus, if he wanted 300+ hp out of it, he could throw on a set of Hooker headers, an Edelbrock intake, and a good Holley 700cfm carb, along with those Flowmaster 2 chamber mufflers. Simple and wuick bolt ons He wouldnt even have to deal with finding better heads, beacause the heads on it are already great.
